required level of Java
use by Library Server administrators and IBM support personnel.
Library Server usability enhancements are planned for user interfaces, including
improved navigation between certain dialogs, modernized icons, and descriptive
hover popups for documents on a shelf.
• SDSF is planned to augment the CK panel by displaying recorded checks on a new
health check history panel. The default will be to display up to ten prior iterations
of each check from the log stream, and support is planned to allow you to browse
and print check output from the history panel as you can on the primary CK panel.
• SDSF is designed to support displaying information about printers for JES3, and to
eliminate the requirement for WebSphere® MQ when displaying JES2 MAS-wide
data on the initiator panel for JES2 once all systems in the MAS are at z/OS V1.12
JES2. Also, displaying MAS-wide data on the printer panel for JES2 is planned not
to require WebSphere MQ when all systems in the JES2 MAS are at or above z/OS
V1.11 JES2.
• In z/OS V1.12 a new DISPLAY XCF,REALLOCATE,TEST option is planned to
simulate the reallocation process and provide information about changes the
REALLOCATE command would attempt to make, and any errors that might
be encountered if an actual REALLOCATE process were to be performed. This
capability is intended to provide information you can use to decide when to invoke
the actual REALLOCATE process, and also whether you may need to make any
coupling facility configuration changes before issuing the actual REALLOCATE
command. A new DISPLAY XCF,REALLOCATE,REPORT command is also planned,
to provide detailed information on the results experienced by a previously
executed REALLOCATE command. This capability is intended to help you find such
information without searching through the system log for REALLOCATE-related
processing and exception messages.
• A number of enhancements are planned to be made to the processing of
PROGxx parmlib members and to Link List Lookaside (LLA) processing. These
include support in PROGxx for passing a specified parameter to a dynamic exit,
automatically including alias names for modules to be placed in Dynamic LPA, and
specifying volumes on SYSLIB for data sets so they need not be cataloged in the
master catalog; a REPLACE option for exits to assure there is no window during
which an exit is unavailable; and a new SVCNUMDEC keyword to specify the SVC
number to be added.
– Additionally, a new DEFAULTS statement is planned, so you can specify
processing defaults intended to help prevent common errors. This includes
allowing you to specify that LNKLST DEFINE always require COPYFROM, that it
default to COPYFROM(CURRENT), and that it automatically process aliases for
modules added to Dynamic LPA.
– LLA processing will be designed to support the use of dynamic LLA exits and to
process multiple MODIFY commands in parallel.
• A new SUMMARY keyword of the DISPLAY SYMBOLS command is designed to
provide summary information about symbols used on the system, including how
many are in use. This can help you determine how many additional symbols can
be defined.
• When a corrupt PDSE is detected in the link list during IPL, the system enters
a wait state. In z/OS V1.12, the system will be designed to issue a message
identifying the corrupt PDSE prior to entering the wait state. This allows the user
to attempt to restore the corrupt PDSE and re-IPL the system and avoid taking a
standalone dump to debug the problem.
• System Logger is planned to be enhanced to correct the VSAM SHAREOPTIONS
for new log stream data sets when it detects that they are not correctly set.
Messages are planned to indicate that Logger has detected and corrected a data
set's SHAREOPTIONS settings. This new function is intended to prevent data set
access problems from arising when SHAREOPTIONS(3,3) has not been set in the
data class used to allocate log stream data sets.
• System Logger is planned to be enhanced to support log data set sizes up to 4 GB
(from the previous 2 GB limit). This applies to both OFFLOAD and STAGING data
set types. As part of this support, System Logger is planned to add messages to
show key data set characteristics at allocation and deletion time. This support is
